Answer:

Sarah = 202.2 points

Robert = 8.4 points

James = 67.4 points

Step-by-step explanation:

James = x point

Sarah = 3x point

Robert = x - 59 point

Total = £11.88

Each point = 3 pence

All students have a total of £11.88

1 pound = 100 pence

£11.88 pound = 1,111 pence

(x * 3) + (3x * 3) + (x - 59)3 = 1,188

3x + 9x + 3x - 177 = 1,188

15x = 1,188 - 177

15x = 1,011

x = 1,011 / 15

x = 67.4 points

James = x point

= 67.4 points

James = 67.4 points

Sarah = 3x point

= 3(67.4)

= 202.2 points

Sarah = 202.2 points

Robert = x - 59 point

= 67.4 - 59

= 8.4 points

Robert = 8.4 points

What is the greatest prime you must consider to test whether 575 is prime
GuDViN [60]

Hello from MrBillDoesMath!

Answer:  23

Discussion:

We only need to check primes less that the square root of 576, which is about 23.98. As 23 is a prime number, it is the answer to the question.

Another way of looking at this: the primes less than or equal to 23

(23*23 = 529)

2, 3, 5,7,11,13,17,19,23

The greatest prime in the list is 23


Thank you,

MrB

How many distinct and real roots can an nth-degree polynomial have?
Vlad [161]
The fundamental theorem of algegra is often cited to say that an n-th degree polynomial has n roots. They may not always be distinct, and they may not always be real.

An n-th degree polynomial may have up to n distinct real roots.
